When to Use This Skill

  • Setting up Faundit webhook handlers
  • Debugging Faundit signature verification failures
  • Understanding Faundit event types (item-status, request-status) and payloads
  • Handling lost-and-found item and request status changes (delivered, finished, expired, etc.)

Verification (core)

Faundit signs each webhook with HMAC-SHA256 (hex) and delivers two headers you care about:

  • X-Faundit-Signature-Nextcurrent (v1) scheme, signs v1:<timestamp>:<body> (payload integrity). Prefer this.
  • X-Faundit-Timestamp — the timestamp used in the signed string.
  • X-Faundit-Signaturedeprecated (v0) scheme, signs v0:<timestamp> only (no body integrity). Avoid.

There is no official Faundit SDK — verify manually. Use the raw request body (before JSON.parse), and build the signed string as v1: + the X-Faundit-Timestamp value + : + raw body.

const crypto = require('crypto');

// Verify the current v1 signature (X-Faundit-Signature-Next)
function verifyFaunditWebhook(rawBody, timestamp, signatureNext, secret) {
  if (!signatureNext || !timestamp) return false;

  const signedContent = `v1:${timestamp}:${rawBody}`; // rawBody = unparsed request body
  const expected = crypto
    .createHmac('sha256', secret)
    .update(signedContent)
    .digest('hex');

  try {
    return crypto.timingSafeEqual(
      Buffer.from(signatureNext, 'hex'),
      Buffer.from(expected, 'hex')
    );
  } catch {
    return false; // length mismatch = invalid
  }
}

Common Event Types

Faundit sends only two event types. The event-type field names the event; the granular status is the data.status field (not a separate event).

event-typeTriggered whendata.status values
item-statusA found/lost item changes statuscontact-missing, waiting-response, wrong-owner, pickup-by-guest, left-behind, finished, shipment-paid, pickup-scheduled, in-route, delivered, deleted, expired, anonymized
request-statusA lost-item request changes statusregistered, not-found, resolved, deleted, expired, anonymized

Payload shape (both events):

{
  "event-type": "item-status",
  "data": {
    "id": 12345,
    "timestamp": "2026-01-15T10:30:00Z",
    "status": "delivered",
    "locationID": "loc_abc123"
  }
}

Note (API v2): Members/faundit_memberID were renamed to Locations/locationID. Legacy IDs are still accepted.

For the full event reference, see Faundit Webhooks docs.
